Spectroscopic Analysis of Hydration Structures in PEG‐ and PMPC‐Containing Hydrogels by Pressure‐Controlled ATR‐IR Combined With Multivariate Curve Resolution

open access: yesSurface and Interface Analysis, EarlyView.
ABSTRACT Hydration structures govern the properties and functions of hydrogels, yet selectively measuring hydration water in the presence of abundant bulk water remains analytically challenging. Here we applied pressure‐controlled attenuated total reflection infrared spectroscopy (ATR‐IR) combined with multivariate curve resolution (MCR) analysis, a ...

MXene‐Based Flexible Memory and Neuromorphic Devices

open access: yesSmall, EarlyView.
The unique two‐dimensional structure, excellent electrical conductivity, and diverse surface groups of MXenes have garnered significant attention. Coupled with their exceptional flexibility, MXene‐based devices hold immense potential for flexible memory and neuromorphic systems. This review comprehensively discusses the fundamentals of flexible devices,

Macroscopic Convective Fluid Flows Arising From Binding of Ions and Small Molecules to Proteins

open access: yesSmall, EarlyView.
The interaction of ions or small molecules with proteins causes convective flows due to the displacement of water from the hydration shell. As shown, the replacement of the nickel ion removed from urease by EDTA pre‐treatment results in binding‐induced convective fluid flow.

Reconciling Granular Hydrogel Microstructure and Mechanics via a Temporary Thermo‐Responsive and Cell‐Invadable Matrix

open access: yesSmall, EarlyView.
Thermo‐responsive granular hydrogels (TRGHs), composed of microparticles and an interstitial matrix, exhibit thermo‐responsive mechanical properties and allow cell infiltration. This system effectively addresses the conventional compromise between mechanical strength and porosity observed in granular hydrogels.

Three‐Dimensional Optical and Computational Reconstruction of Colloidal Electrokinetic Flows via Multiplane Imaging and Multiscale Modeling

open access: yesSmall, EarlyView.
Fast 3D multiplane microscopy is combined with multiscale electrokinetic modeling to reconstruct nanoparticle motion around quadrupolar electrodes. This integrated optical‐computational framework reveals the full three‐dimensional structure of colloidal electrokinetic flows, including localized trapping, depletion layers, and complex vortical motion ...

Dual‐Functionality, Bio‐Friendly Artificial Muscles for Actuation and Motion Sensing in Smart Wearable Systems

open access: yesSmall, EarlyView.
This work presents a biofriendly carbon nanotube yarn artificial muscle operating either as an in‐air unipolar actuator or as a self‐powered ionotronic strain sensor. Using a non‐volatile eutectogel‐derived electrolyte, the system achieves up to 2.9% contraction and 0.5 mV/% strain sensing sensitivity.

Expulsiones «en caliente», devoluciones y petición de asilo en Ceuta y Melilla

open access: yesRevista de Administración Pública
La gestión de los flujos migratorios en la frontera que nos separa de Marruecos está provocando numerosos problemas jurídicos. En este estudio se analiza la legalidad de las formas de devolución directa de emigrantes que se están aplicando («expulsiones en caliente»), así como los problemas que plantea la regulación actual de la legislación de ...

Entre dos expulsiones. Los moriscos granadinos en Andalucía (1570-1610). Propuesta de análisis

open access: yes, 2012
We still do not know much about the morisco minority from Granada, settled in the interior of the Crown of Castile between 1570 and 1610. Even less, unfortunately, for the Andalusian case. The basic objective of this paper is to outline the main lines of future research on the topic, an analysis that will be focus on the social problems generated in ...

Driving Drugs Deeper: Force‐Driven Microneedle Systems for Active Therapy and Their Road Towards Clinical Implementation

open access: yesSmall, EarlyView.
Force‐driven microneedles are presented as active therapeutic microdevices that overcome the diffusion limits of conventional patches. By integrating gas generation, magnetic actuation, cavitation, or iontophoresis, these systems drive payloads deeper into tissue, enabling faster, more controlled delivery and highlighting key design principles and ...
